STREET-PAVING BRICK.

To all whom z'tmaay concern.-

Beit lmown that I, FRANK W. GREBE, a United States, the county of Center and have invented a new and usefulStreet-Paving Brick, of which the following is a specification.

. This invention relates to road-bed construction and ,more particularly to;a brick or citizen of the Philipsburg, in

The object of the invention is to provide an artificial stone brick or block capable of being readily laid to form the surface of a pavement or road-bed, and which may be 1 supported against accidental sinking or displacement Without the employment of the usual curbing. A further object is to provide a reversible brick or block having a vertical seating groove formed in one side thereof and a tongue on the other arranged to enter the seating groove of an'adjacent block when several of said :blocks are laid into a pavement or road-bed, thereby to securely lock 5 the several bricks or blocks against accidental separation.

A further object is to form the bricks or blocks-With mortar-receiving grooves and to provide one side of .each block with spacing 3 0 members arranged to bearsgainst the mating block so as to form an intermediate chamber for the reception of cement or other binding material.

.A still further obfrect of the invention is generally to improve this class of devices so as to increase their utility, d bili and, etliciency.

Further objects and advantages will: ap-- pear in the i'ollowing' description, it being understood that ;various changes in form,

1n the accompanying partof this specification road-bed or pavement.

proportions and .lll lHOIf details of construction may be resorted to Within the scope of the appended claims.

speotive view of a paying brickor block con- 'structed in accordance with my invention. Fig. 2 is a plan View of-several of the bricks or blocks assembled to form the surface of a Fig. 3 :is a transverse sectional View.

Similar numerals of reference indicate corresponding parts in all of the' fig-ures of the drawings.

The improved the pavontient or bricks or blocks 5 forming road-bed are preferably residing at Patented July 27., 190%). Serial No. 476,740.

I substantially rectangular in shape, as shown, and formed of cement, concrete, terras'ot-ta. or other suitable material, said blocks being reversible and having their upper and lower faces provided with a marginal bevel. indicated at 6.

One longitudinal edge of each brick or block is formed with a plurality of spaced vertically disposed seating grooves 7 adapted to receive correspondingly shaped tongues 8 extending laterally from the longitudinal edge of a mating brick or block when several blocks are laid to form a roadebed or pavement, thereby to firmly lock the blocks together and effectually prevent sinking of the .avement or accidental separation of said locks.

Extending" laterally ifirom each brick or "block between t-hesea-ting grooves 3' and also between said grooves and the adfi-acent ends of the block are vertically disposed ribs '9 preferably segmental in cross section nd cunrferenti-al groove 12 which registers with the corresponding groove of a mating brick orblock to form a substantially cylindrical mortar joint or lock 13, as best shown in Fig. 3 of the drawings.

. The mo'rtar-receivmg groove 12 intersects the vertical-grooves 7 and spacing ribs 9 so that when the blocks are assembled to form a pavement the cement introduced within the channels 11 will be guided downwardly be tween the ribs 9 and thus fill the pockets 13 formed by the grooves 12 of. the adjacent bricks or blocks.

It will here be noted that the beveled portions 6 0i the :bricks or blocks -serve to direct the mortar or cement into the channels 11 when filling the same, While the tongues 8 bedisposed in the same horizontal plane the upper surface of the blocks span said channels and thus serve to securely :tie the blocks'together. I

The outer or free end of the tongues 8 are preferably curved or rounded, as indicated at 14, and are held in spaced relation to the curved walls 15 of the seatinggrooves 7, by the ribs 9 so' as to form an intermediate channel or recess for the reception of cement.

If desired, however, the tongues 8 may be whichbear against the smooth unobstructed usual curbing for the pavement or road-bed I may be dispensed with.

While it is preferred to use the the construction of pavements,

blocks in road-beds and the like it is obvious that the same may be used with e ually good results in the construction of bu' dings, dams or other masonry.

It will also be understood that the bricks or'blocks may be made in different sizes and shapes and provided with any number of locking tongues and spacing ribs.

Having thus described the invention what is claimed is 2- 1 I 1. In road-bed construction, a plurality of bricks or blocks laid to break joint and each provided with a vertically disposed tongue adapted to enter a corresponding seating groove formed in an adjacent block, said blocks being formed with circumferential mortar-receiving grooves, and a spacing member secured to each block and arranged to bear against an adjacent block to produce an intermediate channel for the reception of a binding medium.

2. In road-bed construction, a plurality of bricks or blocks laid to break joint and each having one side thereof formed with spaced vertically disposed seating grooves and its opposite side provided with corresponding laterally extending locking tongues arranged to enter the grooves of an adjacent block, and ribs extending laterally from the grooved face of each block and adapted to bear against the tongue-carrying face of a mating block to form an intermediate channel for the reception of a binding medium.

3. In road-bed construction, a plurality of reversible bricks or blocks each having one.

side thereof provided with spaced vertically disposed seating grooves and its opposite side formedwith vertical locking tongues, ribs formed on the grooved side of, each block, there being a circumferential mortarreceiving groove formed in each block arid intersecting the vertical seating grooves and spacing ribs, respectively, said bricks or b ocks being laid to form a road-bed with the tongues of one block entering the grooves of an adjacent block and with the ribs bearing against said mating blocks to produce an intermediate channel for the reception of a binding medium.

4. In road-bed construction, a plurality of reversible bricks or blocks having their upper and lower faces provided with a marginal bevel, one side of each block being rov-ided with spaced seating grooves and t e other side thereof formed with looking tongues, the opposite ends of the locking tongues being disposed in the same horizontal lane with the up er and lower faces of the locks, the severa blocks being laid to break joint with the tongues'of one block entering the seating grooves of an adjacent block, there being a circumferential mortar-receiving groove formed in each block and spaced ribs extending laterally from one side of each block between the seating grooves thereof.

5. A paving brick or block comprising a substantially rectangular body portion having one longitudinal edge thereof formed with spaced vertically disposed seating grooves and its opposite longitudinal 'edge provided with vertical locking tongues extended the entire height of the block, there being a marginal mortar-receiving groove formed in the'block and intersecting the seating grooves and locking tongues.

6. A paving block including substantially rectangular body portion having its up er and lower faces provided with a margina evel, one longitudinal edge of the block being formed with spacedvertically disposed seating grooves and the o posite edge thereof provided with vertical ocking tongues extending the entire height of said block,-there being acircumferential mortarreceiving groove formed in the block and intersecting the seating grooves.

7. A" paving block including a reversible substantially rectangular body portion having its up er and lower faces provided with a margina evel, there being spaced vertically dis osed seating grooves formed in one longitu inal edge of the block and having vertical tongues on either side thereof, the space be tween the tongues being smooth and unobstructed, spacing ribs projecting laterally from. the grooved edge of the block, there being a marginal mortar-receiving groove formed in the body of the block and intersectingathe seating grooves, ribs and locking tongues.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
